Can a chinchilla live after its mate died?

Yes, a chinchilla can live after its mate dies, but it may experience stress and loneliness due to the loss. Chinchillas are social animals, so the absence of a companion can affect their well-being. It's important for the owner to provide extra attention and care during this time, and consider integrating a new mate if the surviving chinchilla is socialized and ready for companionship.
